[0045] In the related art, during the assembly process of the rotor, a plurality of silicon steel sheets are first stacked and extruded to form an iron core, the rotor shaft is mounted on an extension shaft, and the rotor shaft is mounted on an axis mounting device through the extension shaft, and the extension shaft and the rotating shaft are driven toward the iron core through the axis mounting device, so that the rotor shaft is extruded and installed into the through hole of the iron core to complete the assembly of the rotor. Then, the extension shaft is removed from the axis mounting device, and the extension shaft is removed from the assembled rotor.

[0046] However, in the assembly process of multiple rotors, the rotor shaft of a rotor (hereinafter referred to as the shaft to be assembled) is connected to an extension shaft, and the shafts to be assembled of different rotors usually need to be assembled using different extension shafts. Therefore, in the assembly process of each rotor, the extension shaft needs to be installed on the shaft center mounting device, and after the rotor assembly is completed, the extension shaft needs to be removed from the shaft center mounting device, which increases the assembly steps of the rotor and results in low rotor assembly efficiency.

[0047] Based on at least one of the above technical problems, an embodiment of the present application provides an axis installation device, which includes a base and an installation shaft, wherein the base can be fixed to a press, one end of the installation shaft is fixed to the base, and the other end of the installation shaft can at least be used to connect the shaft to be assembled. The installation shaft includes a shaft cylinder, which includes a hollow portion extending in the axial direction, and the shaft cylinder has an air inlet on its wall, which is connected to the hollow portion, so that compressed air can be introduced into the hollow portion through the air inlet.

[0048] When it is necessary to use the shaft center installation equipment to install the shaft to be assembled, the shaft to be assembled can be connected to the end of the installation shaft facing away from the base, and then the installation shaft is used to drive the shaft to be assembled to be vertically extruded and installed into the through hole of the iron core, and the installation shaft is defrosted by compressed air located in the hollow part to remove frost on the surface of the shaft to be assembled, so as to realize the installation process of the shaft to be assembled.

[0049] Compared with the assembly process of the shaft to be assembled in the related art, when installing the shaft to be assembled through the axis installation device of the embodiment of the present application, there is no need to set an extension shaft compatible with the shaft to be assembled, thereby eliminating the installation and disassembly process of the extension shaft, making the assembly process of the shaft to be assembled more convenient and improving the installation efficiency of the shaft to be assembled.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] The following will be combined Figure 1-Figure 8 The axis installation device provided in the embodiment of the present application is described.

[0052] Reference Figure 1-Figure 3 The embodiment of the present application provides a shaft center installation device, including a base 10 and an installation shaft 100, wherein the base 10 can be fixed to a press. One end of the installation shaft 100 can be fixed to the base, and the other end of the installation shaft 100 can be used to connect the shaft 200 to be assembled.

[0053] Exemplarily, the mounting shaft 100 may include a shaft sleeve 110, such as Figure 5 As shown, the shaft barrel 110 may include a hollow portion 111 extending in the axial direction. The shaft barrel 110 has an air inlet 114 on its wall, which is connected to the hollow portion 111 so that compressed air can be introduced into the hollow portion 111 through the air inlet 114 .

[0054] It should be noted that during the assembly of the rotor, multiple silicon steel sheets are first stacked and extruded to form an iron core, the shaft 200 to be assembled is connected to the end of the installation shaft 100 facing away from the base, and then the shaft 200 to be assembled is driven by the installation shaft 100 to be vertically extruded and installed into the through hole of the iron core.

[0055] Since the shaft 200 to be assembled is usually subjected to freezing treatment, frost will form on the surface of the shaft 200 to be assembled. By introducing compressed air into the hollow portion 111 of the installation shaft 100, the frost on the surface of the shaft 200 to be assembled can be removed by the compressed air, thereby realizing the installation process of the shaft 200 to be assembled.

[0056] In some possible implementations, the two ends of the installation shaft 100 along the axial direction include a first end and a second end. The first end of the installation shaft 100 can be fixedly connected to the base, and the second end of the installation shaft 100 is used to connect to the shaft 200 to be assembled.

[0057] Refer to the following Figure 2 and Figure 3 The structure of the shaft to be assembled 200 applied to the installation shaft 100 is described. The shaft to be assembled 200 may be provided with a receiving groove 210, and the second end of the installation shaft 100 may be inserted into the receiving groove 210.

[0058] The accommodating groove 210 may include a first groove section and a second groove section with different inner diameters. The first groove section and the second groove section may be arranged along the direction from the first end of the installation shaft 100 to the second end of the installation shaft 100, and the opening size of the second groove section may be larger than the opening size of the first groove section.

[0059] Reference Figure 2 and Figure 3 In some possible implementations, a limiting hole 112 is provided at one end of the shaft cylinder 110 away from the base, and a limiting ball 113 is provided in the limiting hole 112 . The limiting ball 113 can be movably arranged in the limiting hole 112 along the radial direction of the shaft cylinder 110 .

[0060] At least a portion of the limiting ball 113 may protrude to the outside of the shaft cylinder 110 , so that the shaft 200 to be assembled is connected via the limiting ball 113 located outside the shaft cylinder 110 .

[0061] Exemplarily, the diameter of the hole opening of the limiting hole 112 located on the outer wall of the shaft cylinder 110 is smaller than the diameter of the limiting ball 113, and the diameter of the hole opening of the limiting hole 112 located on the inner wall of the shaft cylinder 110 is larger than the diameter of the limiting ball 113, so that the limiting ball 113 can move radially along the shaft cylinder 110 in the limiting hole 112, the limiting ball 113 will not completely detach from the limiting hole 112, and the limiting ball 113 will not move from the inside of the shaft cylinder 110 to the outside of the shaft cylinder 110 through the limiting hole 112.

[0062] like Figure 3 As shown, when the axis installation device is working in the first state, the limiting ball 113 abuts against the opening of the limiting hole 112 located on the outer wall of the shaft cylinder 110, and the limiting ball 113 partially protrudes from the outer wall of the shaft cylinder 110. The limiting ball 113 located outside the shaft cylinder 110 can be used to connect the shaft 200 to be assembled. When the axis installation device is not working in the first state, the limiting ball 113 does not abut against the opening of the limiting hole 112 located on the outer wall of the shaft cylinder 110, and the limiting ball 113 is located inside the shaft cylinder 110.

[0063] Reference Figure 4 The installation shaft 100 may include a shaft 120 extending along a first direction, the diameter of the shaft 120 is smaller than the inner diameter of the shaft cylinder 110, and the shaft 120 is movably arranged in the hollow portion 111 of the shaft cylinder 110 along the first direction. When the axis center installation device is not working in the first state, a first gap is formed between the hole wall of the limiting hole 112 facing the side of the base 10 and the limiting ball 113.

[0064] Exemplarily, the air inlet hole 114 penetrates the wall of the shaft cylinder 110 along the radial direction of the mounting shaft 100 , and the air inlet hole 114 is communicated with the first gap so that the compressed air from the air inlet hole 114 can flow in the first gap.

[0065] Exemplarily, a movable abutment member 130 is provided in the shaft cylinder 110, and the abutment member 130 may be located in the hollow portion 111. The abutment member 130 may reciprocate along the first direction in the shaft cylinder 110 driven by the shaft rod 120, and the abutment member 130 may include a connecting portion 131 and an abutment portion 132 connected to each other, and the connecting portion 131 may be located between the abutment portion 132 and the shaft rod 120, so that the limiting ball 113 can be driven by the abutment member 130 to move in the limiting hole 112 along the radial direction of the shaft cylinder 110.

[0066] When the axial installation device is not working in the first state, the installation shaft 100 and the shaft to be assembled 200 are in a non-limiting state, the connecting portion 131 and the limiting ball 113 are arranged opposite to each other, and there is a second gap between the connecting portion 131 and the inner wall of the shaft cylinder 110. The second gap is smaller than the radial dimension of the limiting ball 113 along the installation shaft 100. The limiting ball 113 can be located in the shaft cylinder 110, and the limiting ball 113 does not extend out of the shaft cylinder 110, so that the second end of the installation shaft 100 can be more easily separated from the shaft to be assembled 200.

[0067] When the shaft center installation device is working in the first state, the installation shaft 100 and the shaft to be assembled 200 are in a limited state, the abutment portion 132 is arranged opposite to the limiting ball 113, and the two sides of the limiting ball 113 are respectively abutted against the abutment portion 132 and the hole wall of the limiting hole 112, and the end of the limiting ball 113 away from the abutment member 130 is located outside the shaft cylinder 110. The second end of the installation shaft 100 can be inserted into the accommodating groove 210, and the limiting ball 113 abuts against the groove side wall of the second groove section, so that the second end of the installation shaft 100 can be connected to the shaft to be assembled 200.

[0068] It is easy to understand that the movement process of the limiting ball 113 can be achieved by adjusting the position of the abutment portion 132. When the limiting ball 113 is located outside the shaft cylinder 110, the limiting ball 113 can abut against the groove side wall of the second groove section, so that the second end of the installation shaft 100 can be connected to the shaft to be assembled 200. When the limiting ball 113 is located in the shaft cylinder 110, the limiting ball 113 does not extend out of the shaft cylinder 110, and the second end of the installation shaft 100 can be separated from the shaft to be assembled 200.

[0069] By adopting the above technical solution, when the movement process of the limiting ball 113 is realized by adjusting the position of the abutment portion 132, the abutment member 130 can be pulled or pushed along the first direction so that the connecting portion 131 or the abutment portion 132 of the abutment member 130 can contact the limiting ball 113, thereby realizing the movement process of the limiting ball 113.

[0070] For example, the installation shaft 100 and the shaft to be assembled 200 are in a non-limiting state, and the connecting portion 131 is arranged relative to the limiting ball 113. At this time, the abutment 130 can be pulled along the first direction, so that the abutment portion 132 is arranged relative to the limiting ball 113, and the abutment portion 132 can drive the limiting ball 113 to move toward the outside of the shaft cylinder 110 in the limiting hole 112, so that at least part of the limiting ball 113 moves from the shaft cylinder 110 to the outside of the shaft cylinder 110, thereby being fixed to the shaft to be assembled 200 through the part of the limiting ball 113 located on the outside of the shaft cylinder 110.

[0071] After completing the installation process of the shaft 200 to be assembled, the abutment 130 can be pushed along the first direction so that the abutment portion 132 and the limiting ball 113 are offset, the connecting portion 131 and the limiting ball 113 are relatively arranged, and the abutment portion 132 is not tightly pressed against the limiting ball 113, so that the limiting ball 113 can move toward the inner side of the shaft tube 110 in the limiting hole 112, so that the limiting ball 113 is located on the inner side of the shaft tube 110, so that the limiting ball 113 can be separated from the shaft 200 to be assembled.

[0072] Exemplarily, with the plane perpendicular to the first direction as the cross-section, the cross-sectional area of ​​the abutment portion 132 can gradually increase in the direction approaching the second end of the mounting seat, and the gap between the abutment portion 132 and the inner wall of the shaft cylinder 110 gradually decreases, so that the abutment portion 132 can push the limiting ball 113 to move.

[0073] For example, when the axial mounting device is not working in the first state, the mounting shaft 100 and the shaft to be assembled 200 are in a non-limiting state, and the connecting portion 131 is arranged relative to the limiting ball 113. The abutment 130 can be pulled along the first direction toward the first end of the mounting shaft 100, so that the abutment portion 132 can push the limiting ball 113 to move toward the outside of the shaft tube 110 in the limiting hole 112, so that at least part of the limiting ball 113 can move to the outside of the shaft tube 110.

[0074] Reference Figure 2 and Figure 6 In some possible embodiments, when the installation shaft 100 and the shaft to be assembled 200 are in a non-limiting state, the connecting portion 131 and the limiting ball 113 are arranged opposite to each other, and a second gap may be provided between the connecting portion 131 and the inner wall of the shaft cylinder 110, and the second gap may be smaller than the radial dimension of the limiting ball 113 along the installation shaft 100.

[0075] The second gap may be in communication with the first gap, and the compressed air from the air inlet 114 may flow into the second gap through the first gap, so that the compressed air in the second gap may have a certain defrosting effect on the shaft 100 to be installed.

[0076] The second gap is smaller than the radial dimension of the limiting ball 113 along the mounting shaft 100, so that the limiting ball 113 will not move along the first direction in the second gap, thereby ensuring that the limiting ball 113 is always located in the limiting hole 112, reducing the possibility of the limiting ball 113 detaching from the limiting hole 112.

[0077] Exemplarily, when the axial installation device is operating in the first state, the installation shaft 100 and the shaft to be assembled 200 are in a limited state, the abutment portion 132 is arranged relative to the limiting ball 113, and at least part of the limiting ball 113 is located on the outside of the shaft cylinder 110. The compressed air from the air inlet hole 114 can flow to the limiting hole 112 through the first gap and the second gap in sequence, and then can flow out through the limiting hole 112 to realize the defrosting process of the installation shaft 100.

[0078] When the axial mounting device is not working in the first state, the ratio range of the first gap to the diameter of the limiting ball 113 is greater than or equal to 2 / 3, so that at least part of the limiting ball 113 is located in the limiting hole 112, reducing the possibility of the limiting ball 113 getting stuck between the shaft tube 110 and the abutment 130.

[0079] Reference Figure 2 , Figure 3 and Figure 8 In some possible implementations, the mounting shaft 100 may include an adjusting portion 140. The adjusting portion 140 may be disposed at a first end of the shaft rod 120 away from the abutment member 130, and the adjusting portion 140 may be movably disposed on the shaft cylinder 110 along a first direction, so as to drive the shaft rod 120 and the abutment member 130 to move in the shaft cylinder 110 along the first direction through the adjusting portion 140.

[0080] Exemplarily, an elastic member 141 may be provided between the adjusting portion 140 and the shaft cylinder 110, wherein the first end of the elastic member 141 is connected to the shaft cylinder 110, and the second end of the elastic member 141 is connected to the adjusting portion 140, and the adjusting member may be retracted and extended along a first direction to drive the adjusting portion 140 to move in the first direction.

[0081] When the abutment 130 is driven to move along the first direction in the shaft tube 110 by the adjusting portion 140, the adjusting portion 140 can be pulled along the first direction, so that the adjusting portion 140 can drive the abutment 130 to move through the shaft rod 120, and the elastic member 141 is deformed, so that the position of the limiting ball 113 can be adjusted by using the abutment portion 132 and the connecting portion 131 of the abutment 130.

[0082] When the shaft 120 and the abutment 130 need to be reset, the elastic member 141 can be used to drive the adjustment portion 140 to move so that the elastic member 141 returns to its original shape. The adjustment portion 140 can drive the shaft 120 and the abutment 130 to reset, making the use process of the installation shaft 100 more convenient.

[0083] Reference Figure 8 In some possible implementations, the number of the air inlet holes 114 can be set to be multiple.

[0084] The plurality of air inlet holes 114 may be distributed along the circumference of the wall of the shaft cylinder 110 , so that the compressed air from the air inlet holes 114 is evenly distributed between the shaft cylinder 110 and the shaft rod 120 .

[0085] Exemplarily, the air inlet hole 114 can be disposed at one end of the shaft cylinder 110 close to the base, and the air inlet hole 114 can be disposed at the first end of the shaft cylinder 110, so that the compressed air from the air inlet hole 114 can flow toward the second end of the shaft cylinder 110 within the hollow portion 111 and the first gap, so as to heat the shaft cylinder 110 through the compressed air, thereby being able to increase the temperature of the shaft cylinder 110 more quickly, so that the shaft cylinder 110 can remove frost on the mounting shaft 100 more quickly.

[0086] In the installation shaft 100, the shaft rod 120 can be movably inserted in the hollow part 111 along the axial direction, the end of the shaft rod 120 close to the base can extend out of the shaft cylinder 110, and the end of the shaft rod 120 extending out of the shaft cylinder 110 can be connected to the adjustment part 140. The diameter of the shaft rod 120 can be smaller than the diameter of the hollow part 111, so that the movement process of the shaft rod 120 in the hollow part 111 is more convenient, and the compressed air can flow between the shaft rod 120 and the shaft cylinder 110, so that the flow process of the compressed air is smoother.

[0087] Exemplarily, the mounting shaft 100 may include a sealing ring 150. The sealing ring 150 may be sleeved on one end of the shaft rod 120 close to the base, and the outer side of the sealing ring 150 may abut against the inner side of the shaft cylinder 110, so that the hollow portion 111 can be closed by the sealing ring 150, reducing the possibility of compressed air flowing out of the hollow portion 111.

[0088] When compressed air is introduced into the hollow portion 111 through the air inlet hole 114, the sealing ring 150 can block the gap between the first end of the shaft cylinder 110 and the shaft rod 120, so that the compressed air can flow from the first end of the shaft cylinder 110 toward the second end of the shaft cylinder 110, thereby achieving a certain defrosting effect on the installation shaft 100 connected to the second end of the installation shaft 100 through the compressed air.

[0089] For example, refer to Figure 2 and Figure 8 The axial installation device may include a gas pipeline 300, which may be arranged in parallel with the installation axis 100. The gas pipeline 300 has an air outlet 310 on the side facing the installation axis 100, and the gas pipeline 300 can discharge compressed air toward the installation axis 100 through the air outlet 310.

[0090] The number of gas pipelines 300 can be set to multiple, and the multiple gas pipelines 300 can be arranged at intervals along the circumference of the installation shaft 100, so that compressed air can be discharged from multiple directions toward the installation shaft 100 and the shaft to be assembled 200 through the multiple gas pipelines 300, so as to have a certain defrosting effect on the installation shaft 100.

[0091] The multiple gas pipelines 300 may include a first gas pipeline 300a and a second gas pipeline 300b, the first gas pipeline 300a and the second gas pipeline 300b are located on opposite sides of the installation axis 100, and the gas pipeline 300 includes a plurality of gas outlet holes 310, and the plurality of gas outlet holes 310 are arranged at intervals along the axial direction of the installation axis 100, so that compressed air can be discharged toward the installation axis 100 through the plurality of gas outlet holes 310 of the first gas pipeline 300a and the second gas pipeline 300b.

[0092] It is easy to understand that when the shaft 200 to be assembled is installed using the shaft center installation device, the shaft 200 to be assembled is connected to the end of the installation shaft 100 away from the base, and the shaft 200 to be assembled is driven by the installation shaft 100 to be vertically extruded and installed into the through hole of the iron core. Then, compressed air can be introduced into the hollow part 111 through the air inlet 114, so that the inner side of the shaft 200 to be assembled is heated by the compressed air inside the installation shaft 100.

[0093] Compressed air can be discharged through multiple air outlet holes 310 of multiple gas pipelines 300. The multiple air outlet holes 310 are arranged at axial intervals along the installation shaft 100, so that the inner side of the shaft to be assembled 200 can be heated by the compressed air from the multiple air outlet holes 310, so that the inner and outer sides of the shaft to be assembled 200 can be heated through the mutually cooperating air inlet holes 114 and multiple gas pipelines 300, further improving the heating and defrosting effect of the axial center installation equipment on the shaft to be assembled 200.

[0094] To sum up, when it is necessary to use the axis installation equipment to install the shaft to be assembled 200, the shaft to be assembled 200 can be connected to the end of the installation shaft 100 away from the base, and then the installation shaft 100 drives the shaft to be assembled 200 to be vertically extruded and installed into the through hole of the iron core, and the compressed air located in the hollow part 111 is used to heat the shaft to be assembled 200, so as to remove frost on the surface of the shaft to be assembled 200, so as to realize the installation process of the shaft to be assembled 200.

[0095] Compared with the assembly process of the shaft 200 to be assembled in the related art, when installing the shaft 200 to be assembled through the axis installation device of the embodiment of the present application, there is no need to set an extension shaft compatible with the shaft 200 to be assembled, thereby eliminating the installation and disassembly process of the extension shaft, making the assembly process of the shaft 200 to be assembled more convenient and improving the installation efficiency of the shaft 200 to be assembled.
